DAC7644EB/1K

Digital To Analog Converters Overview

The DAC7644EB/1K is a quad, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with parallel data interface and voltage outputs. The device operates on a single 5V supply (4.75V to 5.25V) and achieves a sampling rate of 100 kS/s per channel. Key electrical specifications include a settling time of 10 µs, gain error of 0.08% FSR, INL of ±3 LSB, and DNL of ±2 LSB. Power consumption is 7.5 mW. It is housed in a 48-pin SSOP package and supports industrial temperature ranges from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel 16-bit resolution for multi-axis control applications
• Parallel interface supporting high-speed data throughput
• Integrated reset function to mid-scale output state

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Multi-axis motion control drives and servo amplifiers
• Programmable power supplies and test equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1000 units as documented in distributor specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for surface mount assembly processes. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the official datasheet.

Digital To Analog Converters Selection Notes

Select this component when four independent 16-bit voltage outputs are required with parallel bus connectivity. Compare against serial alternatives like the DAC7634E if board space or pin count constraints favor serial interfaces. Verify that the 10 µs settling time meets the system's dynamic response requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7644 family of precision quad DACs. It serves as the parallel-interface variant within the series, distinct from serial versions like the DAC7634. The EB suffix denotes the SSOP-48 package configuration used for surface-mount technology implementations.

Digital To Analog Converters Replacement Considerations

The DAC7644EB is a direct functional substitute for the DAC7644EBG4. Both share identical electrical parameters and pinouts. Verify package compatibility before substitution.
